Someone in the music scene who listens to bands such as have heart, comeback kid, bane, verse, weekend nachos, etc. Normally wear long sleeve band shirts or any band shirt for that matter, and skinny jeans or tan shorts. There hair is clean cut. Most true hardcore kids are straight edge, but you don't have to be straight edge to be a true hardcore kid. They probably use to be part of the metalcore scene, but got sick of it. When true hardcore kids get in the pit they are usually very stylish with the way they kick and punch the air, and quite often hit someone on accident. They often have huge pile-on's at shows and scream the lyrics to try to get the mic.
